These optical sensors 57a, 57b, 59a, 59b, 61a, 61b constitute a reflection type optical sensor composed of a light emitting element and a light receiving element.

Next, the operation of the golf practice device 1 configured as described above will be described.

First, a method of using the tilting plate 27 in a flat state will be described.

When a flat set switch (not shown) is turned on, a control device (not shown) drives each electric motor 15 to drive the respective first and second jacks 5, 7, 3 and 3. The 4 jacks 9 and 11 are moved downward, for example, until the downward movement limit detector 23 outputs a downward movement limit detection signal. As a result, the tilting plate 27 moves to the lowermost position with respect to the fixed base 3 and is set flat. At this time, the tilting plate detector 25 and the upward movement instruction detector 51 of each of the first and second jacks 5 and 7, and the third and fourth jacks 9 and 11 are provided on the lower surface of the tilting plate 27 set flat. For example, they are in contact with each other and are in an ON state.

When a practitioner standing on the rubber mat 53 sets a ball on the tee 41, the tee up switch or the tee down switch (not shown) is selectively turned on to drive the electric motor 33. Then, the tee 41 is moved upward or downward by the cam body 35 rotating in the upward or downward direction to set the tee 41 to a desired height.

When the tee 41 is moved to the upper limit position or the lower limit position, the electric motor 33 is output based on the detection signal output from the upper tee limit detector 47 or the lower tee limit detector 49. Drive is interrupted.

When hitting the ball set on the tee 41, the swing trajectory of the golf club can be determined based on the detection state of the club head with respect to each of the optical sensors 57a, 57b, 59a, 59b, 61a, 61b. .

That is, as shown by the solid line in FIG. 5, the optical sensors 57a, 57b, 59a, 59b, 61a, 61b arranged in the front-rear orthogonal direction are simultaneously arranged at predetermined delay times according to the arrangement interval. When the club head is detected, the control device determines that the club head is swung in the same direction as the front / rear direction (launch direction), and causes the display device (not shown) of the control device to display a straight line. In addition, as shown by the alternate long and short dash line in FIG. 5, the other rear photosensor 57b precedes the one rear photosensor 57a in the front-rear orthogonal direction, and the one front photosensor 61a the other front photosensor 61b. When the club head is detected earlier, the control device determines that the club head is swung in the trajectory of the hook ball and causes the display device to display the hook. On the contrary, as shown by the chain double-dashed line in FIG. 5, one rear light sensor 57a is ahead of the other rear light sensor 57b in the front-rear orthogonal direction, and the other front light sensor 61b is one front light sensor. When the club head is detected before 61a, the control device determines that the club head is swung on the slice ball orbit and causes the display device to display the slice.

Further, when the ball is set on the tee 41, the position of the tee 41 can be easily confirmed by the light from the light source. Further, even when the surroundings are dark, the position of the tee 41 can be confirmed by the light from the light source, so that the swing practice can be performed even if the ball is not set on the tee 41.

Next, for example, a case of performing a swing practice with a lie with the left toe rising up will be described.

When a set switch (not shown) for moving the toe to the left of the toe is turned on, the control device drives the electric motor 15 of the first jack 5 to raise the first jack 5. At this time, since the electric motor 15 is slidably supported along the inclined surface 13a of the fixed frame 13, the electric motor 15 moves upward with the upward movement of the first jack 5 and the feed screw The connected state of can be maintained.

When the set switch for raising the toe of the left foot of the toe is turned off or a detection signal is output from the upper limit detector 21 of the first jack 5, the control device drives the electric motor 15. It suspends and stops the upward movement of the first jack 5. As a result, only the front right side of the tilting plate 27 is moved upward with respect to the fixed base 3, whereby the tilting plate 27 is tilted to the tilted state corresponding to the lie of the left toe of the toe.

At this time, when the tilting plate 27 is tilted with the upward movement of the first jack 5, FIG. 6 (FIG. 6 shows the relationship between the second jack member 7 and the tilting plate 27, and the third jack 9). (The relationship between the tilting plate 27 and the tilting plate 27 is omitted), a gap is formed between the support bases of the second and third jacks 7 and 9 in the non-driving state and the lower surface of the tilting plate 27. However, as the gap becomes wider, the tilting plate detectors 25 of the second jack 7 and the third jack 9 move away from the lower surface of the tilting plate 27 and transition from the ON state to the OFF state. Based on a signal from the plate detector 25, the electric motors 15 of the second jack 7 and the third jack 9 are driven to tilt the second and third jacks 7 and 9 as shown by the chain line in FIG. Up until the plate detector 25 transitions to the ON state again Move to. This prevents the tilting plate 27 from being destabilized by keeping the second jack 7 and the third jack 9 in contact with the lower surface of the tilting plate 27.

Further, when the tilting plate 27 is tilted to the left toe of the toe as shown by the alternate long and short dash line in FIG. 7, as compared with the flat state shown by the solid line in FIG. And the upward movement instruction detector 51 is changed from the ON state to the OFF state. At this time, the control device drives the electric motor 33 based on the signal from the upward movement instruction detector 51 to move the tee 41 upward. This prevents the balls set on the tee 41 from coming into contact with the upper surface of the tilted tilting plate 27 and falling off the tee 41.

Then, the first jack 5 and the third jack 9 in the case of the toe up, the second jack 7 and the fourth jack 11 in the case of the down of the toe, and the second jack 7 in the case of the down of the toe and the left foot up. , 4th jack 11 for descending toes and left foot, 3rd jack 9 for descending toes and left foot, 3rd and 4th jacks 9 and 11 for descending left feet, etc. By moving the tilting plate 27, the tilting plate 27 can be brought into a tilted state in a desired lie condition.

In the above description, when the tilting plate 27 is tilted by selectively moving the first and second jacks 5 and 7 and the third and fourth jacks 9 and 11 upward and downward, the tilting plate detection is performed. The distance between the device 25 and the lower surface of the tilting plate 27 is detected to selectively drive the electric motors 15 of the corresponding first and second jacks 5 and 7 and the third and fourth jacks 9 and 11 to make the first Although the support base is brought into contact with the lower surface of the tilting plate 27 by moving up the second jacks 5 and 7, and the third and fourth jacks 9 and 11, the tilting plate detector 25 causes the tilting plate 2 to move. Without detecting the separated state with respect to 7, the driving amount of the electric motor 15 in the non-driving state is calculated based on the driving amount of the electric motor 15 that tilts the tilting plate 27, and the electric motor 15 is driven. Support for two jacks 5.7, third and fourth jacks 9/11 The holding base may be always in contact with the lower surface of the tilting plate 27.

In the above description, the swing path is determined by detecting the passing state of the club head by the three sets of optical sensors 57a, 57b, 59a, 59b, 61a, 61b arranged in parallel in the swing direction. Although shown, the head speed is calculated based on the difference in club head transit time with respect to the optical sensors 57a, 57b, 59a, 59b, 61a, 61b and the intervals between the optical sensors 57a, 57b, 59a, 59b, 61a, 61b. It may be calculated and displayed.
